摘要
使用加速量热仪(ARC)研究硝酸异辛酯(EHN)的热分解,得到热分解温度随时间的变化曲线,自放热速率、分解压力随温度的变化曲线以及分解压力随升温速率的变化曲线。分析在绝热条件下硝酸异辛酯的热分解反应动力学和热分解过程,计算表观活化能、指前因子和反应热等参数。根据绝热热分解的起始温度和反应热数据,给出硝酸异辛酯在反应危险度等级中的分类,并计算在75℃时的反应风险指数。
The thermal decomposition of 2-ethylhexyl nitrate （EHN） was investigated using an adiabatic calorimeter called ARC. The curves of thermal decomposition temperature versus time, self - heating rate versus temperature, pressure versus temperature, and pressure versus self - heating rate were obtained. The thermolysis kinetics and decomposition process under adiabatic condition were analyzed, and kinetics parameters such as apparent activation energy, pre -exponential factor and reaction heat were calculated. According to its onset temperature （Tonset） and heat of reaction, the hazard classification of EHN in thermal reactivity was obtained. The reactivity risk index （RRI） at 75 ℃ of EHN was also gained.
